.MACHINE FOR MAKING AXLES.

SPECIFICATION forming part of Letters Patent No. 524,092, dated August7, 1894. Application filed July 6,1893. Serial No. 479.711. (N0 model.)

To all whom it mag concern:

Be it known that I, OAMILL'EMEROADER, of Braddock, in the county ofAllegheny and State of Pennsylvania, have invented a new and usefulImprovement in the Manufacture of Axles, of which the following is afull, clear, and exact description, reference being had to theaccompanying drawings, forming part of this specification, which show ahorizontal sectionalview of my improved machine.

My invention relates to the manufacture of axles, having enlargedportions or collars, and it consists in an improved machine employed inmanufacturing such axles, all as herein} after more fully described andset forth in the claim.

In the drawings, 2, 2, indicate the formingdies, having registeringmatrices 3, which to- .gether compose the mold-cavity within which theaxle is formed. 'These matrices extend the entire length of the dies,the mold-cavity being open at each end and having near the ends annularrecesses 4, 4, to form collars upon the finished axle. At the ends ofthe mold-cavity are located the piercing plungers 5, 5, having roundedends which are adapted to pierce the ends of the blank and force themetal laterally into the annular recesses of the matrix dies. The twosets of plungers are carried by hydraulic cylinders 6, supported in aframework 7, and the method which I employ in connection with thisapparatus is as follows:

A heated blank, consisting of a bar of iron or steel, of proper length,and, if desired, re-

sired for the middle portions of the axle, being placed between theforming-dies, they are forced together, thus forming the intermediateportion of the axle and at the same time clamping the blank securely inplace. The plungers are then forced inwardly, and plercing the ends ofthe blank, force the metal outwardly into the recesses of themold-cavity,

In a machine for making axles, the oombiduced to or approximately to theshape denation with a pair of matrix dies for forming and clamping theaxle blank, of two piercing dies at right angles to the matrix dies andarranged to enter the open ends thereof, and force the metal laterallyto form the collars,

and mechanism for operating said dies; substantially as described.

In testimony whereof I have hereunto set my hand.

CAMIILLE MEROADER.
